At four o'clock in the morning, several people ended their three-hour questioning of Wang Fu.

During this period, they shuffled the order of the same question, interspersed in the long conversation, but each time the answer was different, but the general meaning was the same. Judging from this performance, Wang Fu and Not lying.

During the inquiries, several profiling experts in the next room were also assessing Wang Fu's psychological condition through his body language and his response to some specific questions, but also did not find the characteristics of a serial killer.

When they came out of the interrogation room, the faces of the few people who had stayed up all night for almost another night couldn't hide their tiredness.

It is impossible to find any breakthrough in Gao Wang Fu, and now they can only hope for the physical evidence they brought back from Liu Hongmei's old house.

If the DNA accidentally left by Wang Ting more than 20 years ago can be extracted from those things and compared with the corpse of the first deceased in the corpse dismemberment case, the case may usher in a great progress.

If the DNA matches, it means that their previous guess was wrong, and the deceased is Wang Ting. If the DNA does not match, then the disappearing Wang Ting is suspected of committing a crime.

After returning to the office, Pang Rongsheng immediately asked about the progress of several other groups.

"Bureau, it's not that we are slow, but the questions you gave us are too difficult."

Among them, the group member who was assigned to investigate Liu Hongmei's recent contact with the crowd complained a lot.

Eight, no, it's been another day. Nine days ago, the Kaizhong Science and Technology Park held its 20th anniversary celebration. Several of our park leaders and leaders of several big companies in the science park participated in this event. At the same time, the deputy mayor of Kaiyang City and the deputy directors of other units also attended the event. It can be said that the top leaders of the small half of Kaiyang City all participated with admiration.

Liu Hongmei happened to be one of the cleaners in charge of that event. If she wanted to investigate the people she had been in contact with during that time, it would be tantamount to checking all these leaders.

That’s okay, everyone is in the system, and they all know how bad the social impact of the corpse dismemberment case is. In order to help the police to solve the case as soon as possible, those leaders will also sell their face and accept the investigation. It is rare that some high-tech industry boss.

These people may not be able to sell the police situation, and the more businessmen who cherish feathers, the more taboo they are to be involved in such cases, for fear that they will be reported by the media and their reputation will not be bad.

And these cunning people like foxes can often find reasonable regulations to avoid the police's inquiries. When you find them, all you are waiting for is the gentle refusal of the secretary and the business card presented by the lawyers with a smile.

A day is almost over, and the members of the squad haven't even finished the investigation of the guests who appeared at the event venue nine days ago.

Another day when the progress bar could not be pulled.

Gu Chu did not go to the hotel designated by the Kaiyang Municipal Bureau, but simply squatted on the chair in the office for two or three hours. After 7:30, she went downstairs and scanned the door of the Municipal Bureau. A small blue car, and then came to Kaizhong Science and Technology Park alone, and stood at the door to observe.

When observing every employee who walked into the park to work, Gu Chu was thinking about a problem.

Assuming that Liu Hongmei's death was really because she saw someone she shouldn't, or knew something she shouldn't know, then between Liu Hongmei and the murderer, who had been at peace for more than 20 years, there must have been some kind of incident. intersection.

Liu Hongmei has been cleaning the Kaizhong Science and Technology Park for more than three months. On weekdays, the cleaning work area she is responsible for is mostly in the West District, so Gu Chu chose to stay at the entrance of the West Gate of the Science and Technology Park to observe.

The work intensity in Kaizhong Science and Technology Park is very high, and ordinary white-collar workers almost all follow the unspoken rules of 996, and some even reach 997, and there may only be one or two days of rest in a month. According to the frequency of appearing in the science and technology park almost every day, during the three-month period, Liu Hongmei had a high probability of meeting those people on some occasion in the park.

And Liu Hongmei's strangeness seems to have only appeared in the recent period. If such a change occurs after seeing a special person or event, then it is most likely someone or something that Liu Hongmei rarely sees on weekdays.

Of course, this is just an inference, because small-probability events also exist.

Gu Chu's eyes couldn't help but look at Ximen's bulletin board, which also posted the anniversary celebration poster nine days ago.

During this day, many company executives and Kaiyang city government leaders who seldom appear in the park on weekdays attended the event. People that Liu Hongmei had never met during the three months of working in the science and technology park were extremely rare.It is possible to meet in this celebration.

And the celebration happened nine days ago during the day. That night, Wang Fu came to Liu Hongmei's dormitory to ask for money and had a dispute with her, causing Liu Hongmei to say something like retribution.

From a chronological point of view, it is also reasonable.

Gu Chu looked at the posters, which posted photos of many important guests who came to the scene.

There are men and women, most of them are a little older, after all, it takes a certain amount of time to sit in this position. In the more than 20 photos, only a few are under the age of 40.

Among them, there are six women's photos, they are the secretary of the deputy secretary of the provincial party committee, the deputy director of the Kaiyang Municipal Human Resources and Social Security Bureau, the executives of three technology companies, and the secretary general of the Kaizhong Science and Technology Park.

The oldest of these women is the deputy director of the Human Resources and Social Security Bureau, who is fifty-three years old this year. The youngest is the secretary-general of the park, who is only thirty-two years old this year. The remaining four are between 42 and 47 years old. .

The professional photos on the posters have traces of intensive repair, and they all look like well-maintained and domineering women.

Gu Chu wrote down these names, then turned on his mobile phone, ready to search the Internet for their more daily photos or some clearer videos of participating in activities.

Just turned on the phone, and a call came in.

"There was a landslide in the back mountain of Zifeng Village. The forest guards found some abnormal buried human bones when checking the loss of trees. You should hurry back to the police station now. Forget it, where are you now, just take a taxi and go there. , I'll reimburse you for the fare at that time."

The caller was Pang Rongsheng, and Gu Chu heard a few urgings from him. It seemed that he was about to leave and could not wait for her, so Pang Rongsheng suddenly changed his tone on the phone and asked her to take a taxi.

It can make Pang Rongsheng so anxious, which means that when he reported to the local police station, he provided some information that was very consistent with the corpse dismemberment case.

Gu Chu looked back at the poster, then hurriedly stopped a taxi and rushed to Zifeng Village as quickly as possible.

They only left this small village late last night. Unexpectedly, they arrived today because of the suddenly discovered corpse, but today, the attitude of the villagers is obviously different.

Yesterday they were just sighing because a familiar fellow died, but today they were terrified because three highly decomposed heads and some human bones were found in the back mountain of the village where they lived.

Gu Chu's guess was correct. It was precisely because he learned that there were three severed human heads buried in the skeletons buried in the back mountain of Zifeng Village, that Pang Rongsheng was so excited to bring some of his elites to the scene immediately.

In the three corpse dismemberment cases that took place in Tianjin City that year, the heads of the three victims have never been found. According to today's technology, as long as the skull is found, it can be restored technically, restoring the general appearance of the skull owner when he was alive.

This undoubtedly provides a strong basis for finding victims.

When Gu Chu arrived at the scene, a cordon was already surrounded. Outside the cordon were all curious and scared villagers. A few younger ones even took out their mobile phones to do live broadcasts.

Pang Rongsheng and the others arrived earlier than Gu Chu. Gu Chu took out his temporary work certificate in Kaiyang City and handed it to the police officer responsible for maintaining order near the cordon. After passing the verification, he was allowed to enter the cordon.

"The three heads are all female victims, and the time of death is at least fifteen years. Specifically, I need to collect some biological samples from the surrounding area, and combine the decay of the bones and the comprehensive judgment of the local climate over the years to infer a more accurate death. time."

The forensic doctor is sorting through the bones and remains exposed by the landslide, and now he can only give some basic judgments.

The three heads were all female, and they had been dead for at least fifteen years, which coincided with the three cases of headless mutilation in Jin City that year.

Gu Chu got closer and saw more clearly.

These bones are packed in black plastic bags. The plastic bags are not degradable. After decades, they are still intact. However, the bones in the plastic bags are already highly decomposed, with maggots and worms, and a lot of rainwater that has penetrated over the years , after fermentation, a pungent taste is formed.

The forensic doctor put on a three-layer mask and felt that the stench was overwhelming, not to mention Gu Chu, who had not taken any protection and had a particularly sensitive sense of smell.

But she only frowned slightly, then put on the mask handed over by another police officer, and then walked over to the forensic doctor without changing her face, watching him classify the rest of the bones.

"It's all part of the limbs that Jin City couldn't find back then."

Pang Rongsheng's voice became deeper through the thick mask.

It's no wonder that Jin City was almost turned upside down back then, but the remaining limbs were not found, which turned out to be hidden in another city thousands of miles away.

It is not an accident for the murderer to commit another crime in Kaiyang City after more than 20 years. It is very likely that from the first corpse dismemberment case, the first crime scene has always been in Kaiyang City!

Pang Rongsheng didn't know whether to cry or laugh. It turned out that it was not their incompetence, but at the beginning, the conditions for handling the case at that time limited the scope of their investigation, but it was also their incompetence.

All inspections were carried out with a red light and expedited processing. The inspection results of those skeletons came out. They were indeed the heads of the three victims in Tianjin City. At the same time, the photos of the three victims whose skulls were recovered also appeared in their hands. .

Because Wang Ting disappeared in 1994, she lived in a poor and patriarchal family again, and she didn't have a photo of herself until she left the family at the age of 21.

The first-generation ID card was only produced in 1995. There was no photo of the holder on the account book used before. Therefore, to identify Wang Ting’s identity, we could only rely on Wang Fu and other relatives and neighbors she used to get along with. .

Wang Fu was still left in the police station. When Pang Rongsheng and Gu Chu handed Wang Fu the recovered photo of the first deceased, his expression changed immediately.

"Wang, Wang Ting?"

After all, I hadn't seen each other for more than 20 years. Suddenly, when I saw a restored photo that looked very similar to the year when my sister ran away from home, Wang Fu was still a little unsure.

Is it really Wang Ting?

Pang Rongsheng and Gu Chu's hearts sank, and then, the inspection results of some of the physical evidence found in the Wang family's old house came out. Although the extraction was very difficult, the inspectors still tried their best to extract some tissues from those things. And a DNA comparison was done with the bones of the first victim, and it was indeed the same person.

In other words, the first victim was definitely Wang Ting who lived in that house back then, and there was no so-called wrong oolong.

Gu Chu's guess was overturned!

To make matters worse, Gu Chu felt the reminder from the mission book that she was about to embark on the next mission.
